Ochil follows the curve on Tiree
Denny based Ochil Timber supplied specialist roof trusses for an intriguing architectural project on the island of Tiree, where two spacious family homes were constructed, and another extended, each featuring a unique curved roof. The homes, constructed by Cornerstone Construction Scotland Ltd, were described by Jocky Bryce of Cornerstone, as:
“An opportunity to build efficient modern homes in a style which pays homage to some of the traditional architecture you find on Scottish islands.” Commenting specifically on the curved roofs he said: ”The use of curved roofs in this part of the world is a direct response to the weather conditions you get here, to the exposed nature of sites and the wind speeds that buildings have to withstand. Traditionally the roof trusses would all have been hand– made, but by using Ochil’s prefabricated trusses we saved several man hours on each job.”
Ochil Timber supplied the timber trusses for all three curved roofs, and Andrew McAree, MD of Ochil, confirmed that the non-standard nature of the roofs presented some challenges. He explained: “Usually people think trussed roof rafters are all about angles. This proves pre fabricated trusses can be used for many different shapes, including curves. By plotting the exact placement of the joints on the trusses we were able to deliver a perfect curve on the external surface of the finished roof.”
In addition, it was important that the internal spaces and dimensions of the dwellings as envisaged by the architects were maintained, and the use of attic trusses by Ochil ensured that usable “room in the roof” space could be included. Once the trusses were erected, a process which Mr Bryce said went “Perfectly, no problems whatsoever”, the roofs were finished with sarking, felt and several layers of Evopaste and scrim, ensuring they were entirely weatherproof. All three houses provide thoroughly modern homes which also fit perfectly with island traditions. Over the course of the project Ochil supplied 56 trusses to Tiree, all of which were manufactured in their Denny factory from sustainably sourced timber.
